Hi,
I have a dataset where currently missing values are
labelled 99 for all variables (which usually have
values between 1-15). Is there anyway I can get stata
to recognize the value 99 as missing variables so that
they are not included in tables or in regression?
Thanks,
Ashwin

See -help missing- and -help mvdecode-. Basically, you'll want to
recode the missings to one of Stata's mv codes, which are ., .a, .b, ..., .z.

Commands like -findit missing values- will help you to hunt this sort
of stuff down.
